SU1382745A1 - Bulk cargo feeder - Google Patents

Abstract

The invention relates to devices for the movement of wet bulk cargoes and may find application in loading and unloading operations. The purpose of the invention is the dehydration of the transported cargo. Tray 1 is provided with a bottom 2, which is made of a moisture-permeable material. Under the bottom 2 there is a plate 3 with a drain valve 5, which is connected to the tray 1 by means of flexible walls 4 and with a fixed base by means of a pull. During the reciprocating movement of the tray 1, the hermetic cavity formed by the plate 3 and the walls 4 changes its volume due to the flexibility of the walls 4, as a result of which moisture from the transported cargo is sucked into this cavity through the bottom 2 and is drained from it through the valve 5. 2 silt c & (L

The invention relates to loading and unloading equipment, namely to the transport of bulk materials.

The purpose of the invention is the dehydration of the transported cargo.

Execution under the water-permeable bottom of the tray, through which the cargo is transported, is closed in a sealed cavity, the volume of which changes during the reciprocating movement of the tray, allows pumping moisture from the cargo.

Figure 1 shows the feeder, a general view; figure 2 - section aa in figure 1.

Tray 1, installed with the possibility of reciprocating double door, has a moisture-permeable bottom 2. Plate 3 is connected to tray 1 by flexible walls 4. The bottom 2, plate 3 and flexible walls 4 form an airtight cavity B under tray 1. Plate 3 has a non-returnable the drain valve 5 and is pivotally connected to the fixed base of the thrust 6, and also connected by the hinge B to the tray 1 with the ability to perform a reciprocating rotational movement relative to the hinge B.

The feeder works as follows.

When the tray 1 moves forward, the volume of cavity B increases due to the fact that plate 3 is held tight 6, and flexible walls 4 are stretched. In cavity B, a vacuum is created in the air, and the liquid from the bulk material located in tray 1 is otx827452

sucks through the moisture-permeable bottom 2 and into the cavity B.

When the feeder moves backward, the volume of cavity B decreases, and air flows through the bottom 2 under the material being transported, forming an air lubricant and at the same time cleaning the pores clogged by the material. Together with that

0, liquid is removed from cavity B through a non-return drain valve 5.

Thus, the feeder allows simultaneously with the transportation process to suck the pore water from the cargo due to periodically created air dilution in the sealed cavity under the feeder tray, which significantly reduces the mass of the cargo that is subject to further transportation and increases the efficiency of vehicle use.
